MANUFACTURING METHOD FOR RECYCLED AGGREGATE USING SLUDGE AND CONCRETE PRODUCTS THEREOF
The present invention relates to a recycled aggregate forming method using sludge and a concrete block using the same. The recycled aggregate forming method using sludge includes: a mixed sludge forming step of forming mixed sludge by mixing various kinds of sludge at a predetermined ratio; a mixture evaporating step of evaporating moisture contained in the mixed sludge by mixing industrial byproducts having exothermic feature with the mixed sludge; a drying and evaporating step of drying the mixed sludge, from which moisture is evaporated in the mixture evaporating step, at 100-200°C; and a sintering and dehydrating step of sintering the mixed sludge, dried in the drying and evaporation step, at 650-1,000°C. Various kinds of sludge in the mixture sludge forming step include centrifugal concrete sludge, ready-mixed concrete sludge, stone sludge, and sewage sludge. The present invention is expected to improve the durability and strength of a concrete block using a recycled aggregate by removing moisture, a chemical material, or an organic material contained in sludge in phases to form the recycled aggregate.
본 발명은 슬러지를 이용한 순환골재 형성방법 및 이를 이용한 콘크리트블록에 관한 것으로, 여러 종류의 슬러지를 일정 비율로 혼합하여 혼합슬러지를 형성하는 혼합슬러지형성단계, 발열성을 갖는 산업부산물을 상기 혼합슬러지에 혼합하여 상기 혼합슬러지에 함유된 수분을 증발시키는 혼합증발단계, 상기 혼합증발단계에서 수분이 증발된 혼합슬러지를 100 내지 200℃에서 건조시키는 건조증발단계, 상기 건조증발단계에서 건조된 혼합슬러지를 650 내지 1000℃에서 소성시키는 소성탈수단계를 포함한다. 상기 혼합슬러지형성단계에서 여러 종류의 슬러지는 원심력콘크리트슬러지, 레미콘슬러지, 석재슬러지 및 하수슬러지를 포함하며, 본 발명에서는 단계적으로 슬러지에 함유된 수분, 화학물질 또는 유기물을 제거하여 순환골재를 형성하여 상기 순환골재를 이용한 콘크리트블록의 내구성과 강도 향상을 기대할 수 있다.
